Comments on: SQL SERVER – Recover the Accidentally Renamed Table

There is another method that I use on all my production instances. A DDL trigger fires whenever a DDL action is performed, in this case the renaming of a table. The results gathered by the trigger are stored in a table that logs the statement including the table name before and after.

This technique works whether a SQL statement is physically typed in or performed in the SSMS with a right mouse click.

The only other solution is to wait until a user tries to do something and fails. Look at the query and figure out which part is broken, your number 3 I believe.

We can view this changes in SQL Server Logs under Management in SSMS.

+1 to Imran’s method. You might also be able to recover it from the system_health session. Finally, run something like Event Notifications.

This can easily identified if we have followed standard in our coding.
For example, if we have created INDEX with naming convention like ‘IX_TableName_Colms ‘ from here we can easily get the name of the Table before change.

If we have a change data capture enabled on the DB, then i think we can check what the Table name was before being renamed

Try your application that works with the database. It might give you an error like ‘table … doesn’t exists’ in the logfiles.

It was a long time ago, but, I came so close to doing this myself once. With this article handy, there is a chance of recovery if I ever happen to mess things up again.

Use a script like this to list all the tables in the schema then look for the ‘missing’ table:

SELECT
SUBSTRING(o.name,1,50) AS TableName
FROM
sysobjects o
ORDER BY
1 ASC

Another option similar to 5 would be to use the Red-Gate tool Sql Compare. Sql Compare can use a backup file as the source. The compare will tell you the differences with out having to actually do the restore. Depending on the size of the database, it will take a while to read thru the backup file to pull out the schema.

It can also be recoverd from the SQL Server log.

For Example :

SELECT [RowLog Contents 0] FROM sys.fn_dblog(NULL, NULL)
WHERE Context IN (‘LCX_MARK_AS_GHOST’,'LCX_INDEX_LEAF’)
AND Operation in (‘LOP_DELETE_ROWS’,'LOP_INSERT_ROWS’)
And AllocUnitId IN (562949955649536)

And [RowLog Contents 0] need to be decoded and get the before and after renamed table name.

Here is the solution :

User can refer the queries in which he/she thinks might have used that table and find the missing entry in the database i.e., table name present in query but not in database.

If we have latest (full + differential + log) backup, restore it to some different instance (or on same instance with different database name) and do the schema comparision. This will give the difference of table name.
